Provided is a method for producing a dicyclopentadiene-modified phenolic resin, in which resin properties and the color tone stabilize when a catalyst is repeatedly used and the catalyst can be repeatedly used enough times. The method for producing a dicyclopentadiene-modified phenolic resin includes reusing a fluorine-based ion-exchange resin as a catalyst in a reaction between a phenol and a dicyclopentadiene, the fluorine-based ion-exchange resin having been used as a catalyst when a phenol and a dicyclopentadiene are allowed to react with each other to produce a dicyclopentadiene-modified phenolic resin. In the method, the fluorine-based ion-exchange resin to be reused, the fluorine-based ion-exchange resin having been washed with an organic solvent, is used at least once when reused. Also provided is a production method including purifying a product, the method being capable of preventing coloring of a resin obtained in the production of a dicyclopentadiene-modified phenolic resin. The dicyclopentadiene-modified phenolic resin obtained by the production method of the present invention has a stable quality and a high purity and is inexpensive.
